A student shoots a dart upwards at an angle 30.0° from a height of 2.00 m above the ground. The dart lands 15.0 m away from the student. With what speed did the dart leave the dart gun

A dart gun is fired while being held horizontally at a height of 1.00 m above ground level and while it is at rest relative to the ground. The dart from the gun travels a horizontal distance of 5.00 m. A college student holds the same gun in a horizontal position while sliding down a 45.0° incline at a constant speed of 2.00 m/s. How far will the dart travel if the student fires the gun when it is 1.00...
A child fires a foam dart from a dart gun. The dart initially travels with a speed of 6.00 m/s horizontal to the ground. The dart strikes the ground at a horizontal distance of 2.00 m from where the dart was fired. How high above the ground was the dart when it was fired?
A cannon shoots a cannonball from the ground level (ignore the height of the cannon) towards a cliff of height h = 170 m. The cannonball is launched with an initial velocity of 110 m/s at an angle of 64° above the horizontal. Neglect air resistance. Assume the cannonball hits the cliff as it descends (on its way down) exactly at the edge, as shown. a. Determine the maximum height above the ground reached by the cannonball.b. What speed will the...
A spring-powered dart gun is un-stretched and has a spring constant 150 N/m. The spring is compressed by 8.00 cm and a 5.00 gram projectile is placed in the gun. The maximum height of the projectile when it is shot at an angle of 30.0 degrees above the horizontal from the gun is...?
A balloon filled with water is dropped from a height of 20.0 m. At the same time, a dart is fired straight up from the ground below the balloon. The initial speed of the dart is 15.0 m/s. When does the dart hit the balloon and how high above the ground does the dart hit the balloon? Assuming that the balloon breaks instantaneously and that the dart doesn’t affect the motion of the water, how long after the balloon breaks...
A projectile is fired from the ground, reaches a maximum height of 50.8 m and lands a distance of 39.1 m away from the launch point. What was the projectile s launch velocity? You launch a projectile toward a tall building, from a position on the ground 39.3 m away from the base of the building. The projectile s initial velocity is 45.9 m/s at an angle of 58.7 degrees above the horizontal. At what height above the ground does...
An archer shoots an arrow from a height of 1.19 m above ground with an initial velocity of 44.3 m/s and an initial angle of 36.7degree above the horizontal. At what time after the release of the arrow from the bow will the arrow be flying exactly horizontally? (in s) 2.6988 3.5893 4.7738 3492 8.4444 11.2311 14.9373 19.8667
Projectile Motion A student performs the projectile motion experiment, shooting a steel ball with a purely horizontal initial velocity from a spring gun. The ball lands a horizontal distance of 1.53 m away from the barrel of the gun, and the gun is a height of 1.44 m above the ground. What is the initial velocity of the ball?
A fireman d = 30.0 m away from a burning building directs a stream of water from a ground-level fire hose at an angle of θi = 28.0° above the horizontal as shown in the figure. If the speed of the stream as it leaves the hose is vi = 40.0 m/s, at what height will the stream of water strike the building?
An airplane is flying at a height h, above the ground when it shoots a projectile with v. = 80 m/s at 24° below the horizontal as shown in the figure. Please assume that the projectile is in free fall while it is in the air. a) How long would it take for the projectile to accelerate to a speed of 110 m/s? b)lf the package lands 1 km from where it was shot, at what height is the plane...
